Starting with nightly build 2024.09.28, the Manifold geometry backend is no longer experimental: It’s now possible to choose between the two geometry backends in Preferences->Advanced->3D Rendering->Backend.
For cmd-line usage: openscad --backend=manifold
CGAL is (for the time being) still the default backend.
Thanks to @ochafik for spearheading this, and to the Manifold team for being very supportive and engaging actively with the OpenSCAD community!
@OpenSCAD why hasn’t theee been a new release for the Mac in 3 years? Are we just supposed to use the nightlies?
